  • AI features summarize unread channels and threads, reducing catch-up time after time away
  • Free tier's 90-day message history limit means older context becomes permanently inaccessible
  • Can contribute to notification overload and "always-on" expectations without deliberate norms
  • Per-user pricing adds up significantly for large organizations
  • Channel sprawl in large organizations can fragment information across too many places
  • Microsoft Teams' bundling with Microsoft 365 creates strong pricing competition for budget-conscious buyers
